Event it´s a robotic arm mobile controlled by bluetooth from an app
Step 1: Sevent App
I will make a video of this ok you can follow me in my social networks.
please visit my blog:
The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
Step 2: Robotic Arm
You will need a robotic arm structure and 5 servos(15kg)
Step 3: Arduino Mega
you will need an Arduino Mega 2560
Step 4: Gift
here we have some gifts
Step 5: Model
look for a papercraft
Step 6: Depp_mau
i will make videos of this just be pacience
